Update 23-Jan - added support for WN6 rating (from US server).Also for whoever has a long battle history in the database now the PR for last ~1000 battles appears as well in the profile.Update 5-Jan - Moved NoobMeter to new server. New feature - Inputting two or three names (delimited by commas, spaces, whatever) brings up a comparison screen.
Update 23 Dec - scatter charts for clans.
Update 20-Dec: Added more kinds of server top lists.
Update 18-Dec: added graphs in player and recent result pages if enough data is available
Update 16-Dec: added initial support for viewing your recent results in slightly more detail (if it is available in database).
Update 12-Dec - Added viewing by clan (only for players in DB / viewed since clan viewing was added).Update 11-Dec: New version in, fixes some issues with people's alt accounts getting to top of server list too easily. Should not have no impact whatsoever on most peoples ratings.
Update 01-Dec: Added "Server Top" feature (from players updated in the database).
Update 24-Nov: Now showing Performance Rating for recent battles for those players who have at least 25 of them in the database. Due to sample size, of course, results can vary.
Update 20-Nov: new version deployed with:

Greetings,
This is the official EU thread for NoobMeter - a World of Tanks statistics tracking website with all sorts of awesome features:http://noobmeter.com/Q. What is this?
A. This site calculates the "performance rating" for the World of Tanks players you specify.
It is currently in alpha stage (early release).Q. What is the performance rating?
A. It is a calculated value assessing the player skill, based on an assessment of the tanks the player is playing, the damage dealt (considering tanks played!) and the win rate.Q. How is the performance rating better than efficiency rating?
A. It is a more accurate assessment of player skill, as it focuses on two values which are hard to boost together - damage dealt, and win rate (CW/TC can boost win rate but will lower damage dealt). A player generally cannot improve these two values without directly helping his team, thus there is no way to selfishly inflate the performance rating values.Q. What are the issues with efficiency rating?
A. Efficiency rating is flawed in many ways and allows players to boost it if they focus on simply doing things which increase the efficiency rating.
In particular, it over-values capping and initial spotting, and players who mostly worry about efficiency rating ruin games for others by 'ninja-capping' or 'suicide-spotting'.
For example, a player on the EU server has the absurd efficiency rating of 16,505 attained in exactly one battle in a 'loltractor'. Such examples are plenty.Q: Many players with high efficiency rating also have a high performance rating, so what is the point?
A: Good players that care for their team and help winning have both high efficiency rating and performance rating. Only players who artificially boost their efficiency without helping their team get a lower performance rating.
So for the majority of players these two values will indeed correlate.
Also note that the scales of ER and PR are different (see below)!Q. Can you publish the exact formula for performance rating?
A. Not at this point. It is a complex algorithm, not a formula, so would involve publishing the source code.
However, the main things it looks at are:

What damage have you done? This has the most impact, and is evaluated considering what tanks/tiers are played.

What is your win-rate?

It also does some adjustments in case of very low number of battles played and other special cases.Q. I think the performance rating of player X is wrong, it should be higher/lower.
A. Please post the player name in this discussion thread and we will evaluate.Q. What are some general guidelines for evaluating performance rating?
A. In general, although these may be reevaluated later:

Less than 1150 - bad player

1150 to 1250 - below average player

1250 to 1450 - average player

1450 to 1750 - good player

1750 to 1950 - great player

1950 to 2000 - excellent player

More than 2000 - "Unicum"

Q. Can you add parameter X to the performance rating?
A. WarGaming only publishes a limited set of data to their web site, which limits the options. Of these, we have chosen the parameters that are the most relevant to evaluating player performance, and ignored others such as initial spotting, cap points and average experience as they are either too easy to boost or are too inconsistent (e.g., depend on presence of premium account).Q. Why are you not including kills per battle?
A. Kills are sufficiently accounted for in damage and winrate. Any kill helpful to the battle effort will indirectly raise the winrate and any kill by definition increases damage.
It just introduces another variable to muddle things up for no great advantage. And it could encourage someone to actively kill-steal.Q. Why are you not including defence points?
A. Any defence helpful to the battle effort will indirectly raise the winrate, and is thus already accounted for in the rating.
Including it could encourage people to "farm" defence points by waiting for enemy to cap longer before resetting if the situation permits doing it safely.Q. Why are some people so angry in this thread and/or are trolling?
Usually, because their performance rating is lower than they believe they deserve. And usually that is because they have gamed / boosted their efficiency rating.
We'll be very interested to hear your comments!Edit - recreating thread as original has disappeared, probably it was closed due to a few posters misbehaving.Thread moved to more appropriate section of the forums. Please use appropriate forum sections when creating new topics.---Orree

Very nice tool which gives exactly what people should be concentrating on, PERFORMANCE, but can you add a new value, "Enemies destroyed / Battles participated", I mean what use are you for the TEAM if you cant get at least one enemy per match at average, (of course you can be a scout and thats usually different and selfchosen tactic / tank choice).
Its probably easier for you to just put in a new field and divide the two different values from the WOT server, and put them at the top of the list, I think that it probably useless to write to WG about this.

Less than 1150 - bad player
1150 to 1250 - below average player
1250 to 1450 - average player
1450 to 1750 - good player1850 to 1950 - great player
1950 to 2000 - excellent player
More than 2000 - "Unicum"
and what is betwen 1750-1850? Im a very good bad boy?

A. In general, although these may be reevaluated later:
Less than 1150 - bad player
1150 to 1250 - below average player
1250 to 1450 - average player
1450 to 1750 - good player
1750 to 1950 - great player
1950 to 2000 - excellent player
More than 2000 - "Unicum"
Q. Where can I find more information about this tool, including a more extensive Q&A list?
